Method for Initializing Newly Added Base Station in UWB System, Terminal, and System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18263379 titled 'Method for Initializing Newly Added Base Station in UWB System, Terminal, and System

Simplified Explanation

The method described in the abstract involves a device in an area that requests a UWB base station to measure an initial position, then moves to another area to measure distances between UWB base stations and at least three locations. The device then returns to the original area, requests the UWB base station to measure an end point position, and corrects its coordinates based on the measured end point position. The coordinates of each UWB base station in the area are calculated based on the corrected coordinates and the measured distances.

• Device requests UWB base station for initial position measurement
• Device moves to new area and measures distances between UWB base stations and locations
• Device returns to original area and corrects coordinates based on end point position
• Coordinates of UWB base stations are calculated based on corrected coordinates and measured distances

Potential Applications

This technology could be applied in various fields such as indoor positioning systems, asset tracking, and location-based services.

Problems Solved

This technology solves the problem of accurately determining the position of a device in an area by combining UWB measurements with IMU data.

Benefits

The benefits of this technology include improved accuracy in determining device location, enhanced tracking capabilities, and potential cost savings compared to traditional positioning methods.

Potential Commercial Applications

One potential commercial application of this technology could be in the development of indoor navigation systems for large facilities such as airports, shopping malls, or warehouses.

Possible Prior Art

One possible prior art for this technology could be existing methods of indoor positioning using UWB technology combined with other sensors for enhanced accuracy.

How does this technology compare to other indoor positioning systems on the market?

This article does not provide a direct comparison with other indoor positioning systems, so it is unclear how this technology stacks up against existing solutions.

What are the limitations of this technology in terms of accuracy and scalability?

The article does not address the potential limitations of this technology in terms of accuracy over long distances or scalability for large indoor spaces.

Original Abstract Submitted

A method includes a device in an area that requests a ultra-wideband (UWB) base station in the area to measure an initial position, and starts inertial measurement unit (IMU) measurement. The device moves to an area , and the device requests to measure distances between each UWB base station in the area and at least three locations. The device returns to the area , and requests the UWB base station in the area to measure an end point position. The device corrects coordinates of the device in the area calculated using data obtained through the IMU measurement based on the measured end point position. Calculate the coordinates of each UWB base station in the area based on the corrected coordinates in the area and the measured distances between each UWB base station and the device in the area
